To all whom 'it may concern:-

lBe itAv known that l, yWAsHiNG'roN I. PHIIER, a citizen .of the UnitedStates of America, residing at Collinsville, in the county of Madisonand State of Hlinols, have'invented certain new and useful llmprovementsin Engines, of'which tlie f ollowing is a full, clear, and exactdescription, reference being` had to the accompanying drawings, formingpart'of this speciiication.

This invention `relates to engines havin istons reciprocable underpressure derive rom any suitable duid which is introduced into cylinderswithin which said pistons are operated, and has for its primary objectto provide an improved construction, ycombination and arrangement ofparte in devices of this character.

One of the objectsv of this invention is to provide an improvedconstruction according to which an engine of this character may besimply and economically manufactured and rendered durable and ecient inoperation.

Other and further objectswill appear in the specication andbe specicallypointed out in the Aappended claims, reference being had to theaccompanying drawings exemplifying the invention and in which, Figure .lis a longitudinal section through my engine. Fig. Il is a vertical crosssection taken on line H--L Fig. l. Fig. lll is aside elevation of thecam wheel carried by the engine shaft. Fig. llV is an edge view of thecam wheel. Fig. V is a cross section through the cam wheel, taken onlines V--V, Figs. HI and lV.

inasmuch as my engine is designed to be operated by Huid motivepower ofdiil'erent descriptions either in the nature of an explosive agent, orsteam, for example, l do not in the accompanying drawings show means fordelivering. the motive power to the cylinders of the engine, nor thevalves or other ap urtenancesv b which the dei livery. andischarge of te motive power to and from the engine is controlled. Such elements maybe an of those ordinarily used, as will be readi y appreciated upon anunderstanding of the vice to which my invention relates.

ln the drawings: l designates Athe shell of'niy engine, this; shellbeing closed at its ends by cylinder heads 2, thniagh which the motivepower to be used in the engine is admitted and discharged.

Patente ct. i7, i911.

3 designates cylinders arranged in batterf ies within the shell l at theends thereof, and which abut against the cylinder heads 2, one batteryof cylinders appearing most clearly in Fig. lll, while the location ofthe cylinders longitudinally of the shell is shown in Fig. I. Thecylinders in each battery are parallel with each other, and areconnected by spider arms 4 extending radially from a central: hub 5.around the cylinders, which are separated from each other, as seen inFig. Il, is closed at the outer end of each battery by thead-` jacenthead 2, and such space is closed at the inner end of each battery by asuitable wall, thereby providing a `water jacket chamber A, making itpossible to prevent,

overheating of Athe cylinders in which pistons operate, as willhereinafter more fully Y appear. Each cylinder 3 of the engine is closedat its outer end, except for inlet and exit ports, by the adjacent head2, while thev inner ends of the cylinders are in open com-J municationwith a central chamber B.

6 designates pistons operable in the cylinders 3 and movable through theopen inner ends of said cylinders. '-'lhese pistons are arrangedin pairslongitudinally of the engine so that a piston in one of the batteriesmates with a piston of the other battery, and the airs of pistons areunited Iby'connecting ars 7, each of' which is supplied with ananti-friction roller 8.

9 designates a shaft extending longitudinally df the engine, androtatably fitted in the shell heads 2 and, the hubs 5 disposed centrallyof the batteries of cylinders. rlhis shaft extends through the centralchamber B and it has fixed to it a cam wheel 10. The cam wheel 10 isdisposed diagonally of the shaft 9 so that during its rotation its sideface will, at different points, approach and recede from the inner endsof the cylinders 3. In the riinofthe cam wheel is a helical runway. 1lin which the anti-friction rollers 8, carried by the piston connectingbars 7, operate.

In the practical use of my engine, the pis-- tons u on their forwardstrokes carr `with them .the connecting bars 7, uniting t epistons inpairs longitudinally of the engine, and during such ibrward strokes ofthe pistons, the anti-friction rollers 8 by bearing the roller naturallytends to move in the direction of recession of such runway wall. And itis due to this fact that power is transmitted from a piston to the camand the shaft carrying it. It is obvious that while any given'piston isoperating in the manner stated to drive the cam on the engine shaft, thepiston mating with the drive piston works idly during its backwardstroke in so far as power action by the shaft is concerned, and it willbe apparent that when the idle piston has completed its backwardystroke, it is ready in its turn to perform the oince of imparting areverse movement to the connectin bar 7 attached to it for the operationof the cam 10 in the same manner as such oiiice was previously performedb the iston at the other end of the engine. I pre er to employ sixcylinders and six pistons in each battery of such pistons and-cylinders, this being the number illustrated in the drawings, but it isevident that the number of cylinders and pistons may be other than thatshown without departing from my invention.

The essential characteristic features in my engine in so far as theoperation of the engine shaft bythe pistons is concerned, are theprovision of the cam wheel on the engine "shaft having a runway ortrack-way face arranged obliquely relative to the shaft, and means towhich power is communicated in the operation of one or more pistons tothe runway or track surface to -cause rotation of the cam wheel andengine shaft by travel of the means referred to along the runway ortrack surface.

The chamber B in my engine, in which the cam 10 operates, is intended tobe supplied with a quantity of oil in which the cam moves during itsrotation. The oil present in this chamber is continually agitated by thecam, and as a result of a limited degree of heat radiating rfrom thecylinders, the o'il is in a measure vaporized so that it will berendered a most perfect lubricant which is constantly delivered to theworking parts of the engine operating in the chamber B.y

This lubricant, upon being caught by the pistons, is transferred fromthem to the interiors of the cylinders 3 withoutthere being any Waste oflubricant, and without any opportunity of mixture of dirt or foreignmatter W-ith such lubricant. Moreover, the presence of the oil bath. inchamber B,

ing of the cylinders and the pistons operatv ing in them, and I make useof Water delivered into these chambers for swabbing the interior wallsof the cylinders upon each stroke of the piston, by producing in thewalls ofthe cylinders, ducts 12 (see Fig. I), that lead to the interiorsof the cylinders, and provide the pistons with annulargrooves 6 thatreceive water from said ducts when the grooves are broughtintoregistration therewith. In this manner, rings of water are caused tobe constantly present in the annular groovesl in the pistons,l which actwith cooling effect upon thevinterna'l faces of the cylinders, assistingin lubrication of such faces, and further serve asrpacking rings betweenthe pistons and the internal faces of the cylinders.

The herein described construction and arrangement of parts, adapts theengine to develop a maximum amount of power by reason of the largeleverage of action upon the engine shaft, due to the connecting bars 7being disposed on the walls of the pistons farthest from the engineshaft, with the periphery of the cam 9 running between the oppositelydisposed pistons.

I claim: g

l. In an engine, the combination with an outer shell, of batteries ofcylinders disposed at opposite ends of said shell with an oil containingspace between said batteries, a shaft rotatable on an axis centrallydisposed with respect to said cylinders, a cam eyed to said shaft insaid oil space, said cam having its outer periphery extending aroundsaid shaft in a plane inclined thereto and the outer peripheral face ofsaid cam being provided with a runway, a hollow cylindrical pistonreciprocable in each c linder, a connecting member for each pair ofoppositely disposed pistons, said member being secured to the innercylindrical walls of said pistons, and an antifriction roller carried bysaid connecting member and running into said runway.
